EXTENDED HINGE!) ENGINE Application filed January This invention relates to crank ca'sesfor engines, and more particularly for engines onautoinobiles and the like, which extends beyond all the main bearings, has a packing jam screw, hinged cylinder block and an independent carburetor and manifold support and consists in the novel combination and arrangement of parts hereinafter shown, described and claimed.

Heretofore considerable diiiiculty has been experienced in adjusting, repairing and cleaning the working parts of engines on automobiles, by reasons of their inaccessible position.

An object of the present invention, therefore is to overcome this difficulty, and provide an improved casing for the engine, whereby the working parts thereof may be brcught to a convenient and readily accessible position, in order that the same may be conveniently adjusted, repaired and cleaned.

Another object is to provide means for preventing oil leakage around crank shaft of the engine; other objects will be apparent from the following description, taken with the drawings in which- Figure 1 is a side View of the engine showing the ears on the crank case of the engine, the hinges on the cylinder block, and the packing jam screw.

Fig. 2 is a bottom View of the crank case showing how the outer casing extends beyond all the main bearings and the upper half of the packing jam screw.

1 3 a side view of the engine showing the independent carburetor and manifold support and the packing jam screws.

Fig. 4 is a top view of the crank case showing); the piston heads and all the main bearings exposed, the upper half of the packing jam screw and the independent carburetor and manifold support.

Fig. 5 is a front view of the engine showing the details of the hinged cylinder block, packing jam screw and independent carburetor and manifold support.

Fig. 6 is a view of the packing jam screw.

In Figure 1 the cylinder block 1 has a flat smooth surface around the outer edge of the outer side and ends and a smooth diagonal surface on inner side as illustrated in Fig. 5 is made with a hinge 2 on each end and rests upon the upper smooth surface of the main frame 9 which has a set of ears 4 projecting from the side of main frame 9 and spaced so 30, 1925. Serial No. 5,1535.

as to receive the ends of the hinges 2, each set of ears 4: have holes therein which register with the holes near the outer ends of the hinges 2, the holes in the hinges 2 are some larger than the holes in the set of cars 4 so as to allow the cylinder block 1 to tighten all the way around alike when the stud bolts are put in, a hinge pin or bolts 5 is passed. through the holes in the hinges 2 and set of ears 4.

It will be apparent that the bolts or hinge pins 5 on either end may be removed and the cylinder block 1 taken off, the ears l and bolts or hinge pins 5 constituting hinges or pivots on which the cylinder block 1 operates in the' manner illustrated in Fig. 5. 7

Thus it will be observed that the cylinder block 1 may be raised or removed leaving the working parts of the engine exposed to the most convenient and accessible position for cleaning and repairing.

The crank shaft 7 upon which the fly wheel 8 rests passes through between the main frame 9 and the lower part of the c ank case 6 with a packing jam screw 3 at each end, crank case 6 has a smooth surface around the upper edge and is fastened to the smooth surface around the lower edge of the main frame 9 with stud bolts.

In Fig. 2 the bottom view of main frame 9 shows how all the main bearings 11 are exposed for cleaning and repairing and the upper half of packing jam screw 3.

In Fig. 3 the independent carburetor and manifold support 10 is shown connected to the upper half of main frame 9 and is made with a smoothouter edge on the lower surface and a smooth upper diagonal edge on the inner surface as illustrated in F 5.

In Fig. 41: the upper view of the main frame 9 shows how all the main bearings 11 and the piston heads 12 are exposed for cleaning and repairing, the upper half of packing jam screw 8 and the independent carburetor and manifold support 10.

In Fig. 5 is a front view of the entire engine, hinged cylinder block 1, independent carburetor and manifold support 10, packing jam screw 3 around crank shaft 7, passing between the main frame 9 and the crank case 6, supported in the chassis 13 with the hinged cylinder block 1 in vertical position being shown in dotted lines.

The intake manifold 15 and the exhaust manifold 16 are shown in place on the carburetor and manifold support 10 so as to register with the cylinder intake and-exhaust ports, When the cylinder blockis in position for engine operation. V

In Fig. 6 is a'view of the packing jam screw 8 Which is made in two sections 14:

and 15 and so arranged as'to be placed, around the crankshaft 7 and screwed 111 each end of the mainframe 9 and crank case 6.

What I claim and desire to secure'by Letters Patent of-theUnited States is An. internal combustion engine having a crank-case v crank-shaft, and crank-shaftbearings, said crank-case extendingrbeyond all of the said bearings and provided With hinges, a cylinder block mounted to swing about said hinges, said cylinder block being provided with intake and exhaustports, a stationary supportfor the engine intake and exhaust manifolds, the intake and exhaust manifolds being adapted to register With the said cylinder ports When the cylinder block is in position for engine operation.

In itness whereof .I have signed this specification. v
